Resources are mostly grouped into seven "tool kits," one for each SYNC season. All seven are being reworked into a new format for 2023. Only the first four are currently available.
The color-coded, one-page calendar for 2023 shows the seven SYNC seasons spread over twelve months. The seasonal dates change slightly each year because some of the holidays that start or end a season, such as Ash Wednesday, are based on a lunar calendar.
